Internal filter series

PS-638

The PS internal filter series is an artifact integrating oxygen increasing, filtration and nitrifying bacteria cultivation. The shell is made of ABS new raw material of high quality, which is strong, durable, corrosion-resistant, acid-alkaline resistant and of superior performance. The main parts of filter pump head are all made of imported copper wire. The performance is higher and it is more effective to save power. Pouring glue at the top of pump head and sealing could prevent electric leakage safety risks. The PS internal filter is equipped with large area of biochemical cotton and filter cotton. Meanwhile, you can add nitrifying bacteria to the filter cotton to promote the rapid generation of nitrification system, decomposing fish feces and residual food. The filter box can be removed and you can replace the filter material at any time to keep the water clean forever.
